Here at Simply Cool, we love what window tinting can do for the look and functionality of a vehicle. We appreciate that tinting isn’t just for style, but can significantly reduce solar heat while protecting occupants from harmful UV rays on a daily drive. Window tints are fairly easy to spot on a vehicle, but shades can differ greatly. How are those tints measured?

Window tinting is measured by the level of visible light transmission (known commonly as VLT) that is used on any given window. As you can see above, these VLTs are often listed as a percentage. For example, if you’re choosing 20% for the back windows of a car, that means 50% of VLT or visible light will pass through those windows.

What tint is right for you?

It’s simple! The lower the percentage, the darker the tint will be. A low number, like 5% VLT, will produce a noticeably darker film than 50% VLT. Of course, as in every state, there are rules to what VLT percentage can be used on a vehicle’s windows. In the state of Utah, front driver’s and passenger’s side windows should be no lower than 50% VLT. Whereas, back and rear windows don’t have a limit. If you’d like to see VLTs in action together, use the interactive tool above.

Visible Light Transmission Percentage Levels

  • 50% VLT Tint
    With this common tint, fifty percent of visible light will reach the interior of your car. This option is perfect for front windows, or for those looking to block out excess heat and harmful UV rays without compromising visibility.
  • 35% VLT Tint
    Thirty-five percent tint allows for less visible light. This is often considered a “medium tint”. This VLT percentage is excellent for those seeking lower levels of light to reach into the rear of a vehicle, well still having clear visibility day and night.
  • 20% VLT Tint
    Often referred to as “factory tiny”, this tint allows less than half the visible light to reach the interior of a vehicle than the common fifty percent. Although many manufacturers use pigmented glass to offer the same effect, some may not. For those seeking privacy and heat protection in an aftermarket tint, twenty percent is a practical choice.
  • 5% VLT Tint
    The lowest percentage of tint offered by Simply Cool is five percent VLT. Also known as a “limo tint”, this film is the darkest tint on the market. In the state of Utah, fully tinted windows are allowed only on the back and rear windows. For ultimate privacy and sun protection, a limo tint is a way to go.
